Product Description
The Shimano GRX RD-RX815 rear derailleur is a premium 11-speed Di2 gravel derailleur built for smooth, reliable shifting across mixed surfaces. It uses Shimano’s electronic Di2 platform and a gravel-tuned clutch to improve chain stability and shifting confidence on rough terrain.
